导出特定的Active Directory组

Question

Get-ADGroupMember -Id $Group |
  select @{Expression={$Group};Label="Group Name"}, Name |
  Export-Csv C:\Srptupd\Groupmembers.csv -NoTypeInformation -Append

我想尝试导出的群组名称称为＆＃34; IT员工＆＃34;。

每次运行命令时，都会收到此错误：

Get-ADGroupMember : Cannot validate argument on parameter 'Identity'. The argument is null or empty. Provide an argument that is not null or empty, and then try the 
command again.
